I think I was the first one to report the "where in the heck did my 4-low go" post-recall flash, in this thread.

I am happy to report that this morning they performed it again, following the PDF file to the letter.

All transfer case codes are now clear and it functions as it did before the recall was performed.

I did take a printout of the PDF with me to the dealership, just in case.

I also mentioned that according to many JeepForum.com members this is NOT an isolated incident.

The service manager as much as said that although he *had to* say that he was positive the technician must have followed the procedure properly the first time, he would highlight step 15 and reinforce that part to the tech before reflashing it.

A special thanks to R32R1 for putting up the link to the PDF file.

My Jeep is a Jeep again!






Here's a repost of the PDF link, just because.

Went back to my dealer yesterday for recurring "Service 4wd System" message and no 4Lo engagement after 2 previous visits. After a 3rd re-flash, they told me they were going to replace the T-Case Actuator under warrenty. They were going to order one, to arrive today. I went in today, and they told me that Chrysler had cancelled the order. They said that since the recall is new they are still working through these problems. Apparently, Chrysler has identified a problem with defective actuators, and they don't want any more of them out, which is why they cancelled mine. They are underway to resolve the problem. I was told that they will replace mine under warrenty as soon as Chrysler gets the new actuator in production. Meantime, after another re-flash yesterday, my system is operating O.K. Any thoughts? Is this fact or bullcrap? By the way, I did take in that pdf file today, and the service manager seemed up to date with it, including the recommendation to try the procedure 3 times before further actions. Also, my 4Lo is working fine since the yesterday visit, so still baffled about need for T-Case actuator???

Peter Sakai with Customspooling assured me that i can take the Jeep in with the custom tune and it shouldnt be an issue. He states that if they need to reflash the custom tune shouldnt stop them from doing that... though i have a DPF'less tune so i may have a check engine light if they reflash but it should be able to drive home and okay till i can get it reflashed.

Has anyone else gone to the dealer with a custom tune with or without issues?

I talked to my dealer today. They told me that the transfer case actuator is on order, but back ordered, that it may take a month to come in. They will keep me updated bi-weekly. I am trying to get across the fact that this re-flash isn't the cure. Jeep has identified a problem with the t-case actuators. Remember, the recall said the t-case could possibly lose power and shift the t-case into neutral. If you have the code c140, and are getting the service 4wd message, and your jeep won't shift into 4lo, your Jeep may roll on its own. It is becoming an actuator flaw.

Had my Commander reflashed 3 times. Last time it lasted 1 day. My dealer is ordering me a new t-case actuator. They told me today that Jeep has identified the actuators as defective. My new actuator will be replaced under warrenty. But, it is on back order, and may take a while to come in. Obviously, the re-flash wasn't a good fix. The t-case actuators are defective, which is why they could lose power, and shift into neutral. My dealer ordered the existing actuator earlier this week. It was cancelled by Chrysler. My dealer said that Chrysler does not want any more defective actuators on the street!!!

If I understand you correctly this (actuator) is the actual problem? not the cracked boards or is yours just an isolated incident?

I think your dealer's making things up. If the transfer case actuator (shift motor) loses power, it can't move and will be stuck in whatever mode it was previously in; that's 4 hi, in most cases. It also has no power when you're parked, or when you pull the battery to store the vehicle or change the battery.

The transfer case going into neutral requires the shift motor to have power. That's why it's only an issue with remote start or if you're starting with your foot off the brake.

Basically your dealer's telling you you're going to chop your arm off with an unplugged circular saw that has no blade.

So I went back to the dealer today to try and get the 'Service 4WD System' fixed.
Pulled into the parking lot, went out of my car, and dropped my iPod and it cracked.
Happy Saturday.
But the service manager agreed that the recall wasn't performed correctly so they re-reflashed the transfer case and it seems to be working fine now.
Hopefully it stays working.

I don't know who to believe anymore. I am starting to think that my dealer is clueless.

How do you tell a service manager that his shop is doing the recall wrong? My service manager acts like I am the one who is wrong.

But at least it all works now!

I guess my faulty actuator may be an isolated incident, good thing is it is covered by Chryslers 100,000 mile drive train warrenty.

Bring the PDF and have them show you step-by-step that they are doing it 'right'.
